The only time I purchase a book is if I happen to be at my local thrift shop while they are having a four books for a dollar sale.
I haven't been in a book store or bought a book online in over a decade.
I get almost all my reading material from the library website. I haven't been to the library in person in years either. Libby / overdrive is just awesome. I log on to my library website, then see what is available under the "most popular" category. I look at the online summary of what the book is about and then check it out if it appeals to me, or keep scrolling if not. Sometimes It takes an hour or more before I find something to check out. It kind of reminds of the days when we would go to the video store on Friday night and spend more time deciding on a movie to watch than it took to actually watch it.
I am kind of picky about what I like to read. Not interested in zombies or vampires or dragons or ghosts. No Scifi. Prefer books set in the U.S. in modern times. No murders or kidnappings. Would prefer that nobody dies as well, but that seems to eliminate almost all books.
